MACHINE FOR PASTING- THE SEAMS OF CIGARETTES AND THE LIKE.

Specification of Letters Patent.

Patented July 1, 1913.

Original application filed June 24, 1911, Serial No. 635,153. Divided and this application filed October 7,

To all whom it may concern Be it known that I, DANIEL HEMMING, a citizen of the United States, and a resident of the city of New Haven, county of New Haven, and State of Connecticut, (whose 3OSt-O1HCG address is Mechanic street, in said city,) have invented certain new and useful Improvements in Machines for Pasting the Seams of Cigarettes and the Like, of which the following is a specification.

This application is a division of my copending application filed June 24th, 1911, Serial No. 635,153.

My invention has relation to the art of making cigarettes wherein a strip of paper of indefinite length is folded or turned around so as to inclose a continuously formed rod of tobacco in the manner wellknown to the art; and it may also be advantageously employed, by making the necessary modifications, in machines and structures employed for. this purpose which are well understood in the art in the manufacture of cigarettes wherein a n0n-c'ontinuous paper strip and tobacco rod are employed.

As the preferred form of apparatus hereinafter referred to has been designed for use in connection with the continuous paper strip and tobacco rod system I shall describe my invention in connection therewith. In the manufacture of cigarettes so far as I am acquainted therewith it has been the practice to use a soft paste and while in the cold and pasty condition apply it to the cigarette seam and then set the paste and complete and iron the seam under the influence of heat and pressure or by pressure alone. Many difficulties are encountered in the practice of this particular process. The proper consistency of the paste in order to allow it to work under all conditions with the proper amount of adhesive material is very diflicult to obtain resulting in imperfectly pasted or seamed cigarettes entailing loss in the final product and incidental stoppage of machinery in order to regulate the application of the paste. The application of heat in this old way merely dries the paste, presses the device and holds the seam down through the drying operation with the volume of paste, that is the amount applied to the seam, in its thickness, as the Serial No. 653,385.

time of or at the point of application, being more or less' a matter of chance not altogether subject to regulation.

The primary object of my invention is to avoid, these difficulties; to apply the paste in a predetermined amount and to evenly distribute it so that among other things the pasting of a cigarette seam having a I tion accomplished after the paste has been applied and while it is cooling or cold. In other words, in the practice of my invention the paste is applied in a hot and either in a fluid or semi-liquid condition and dried, set and ironed under the influence of cold and pressure instead of heat and pres sure.

My improved apparatus for carrying the same out contains many other advantages which will be apparent to those skilled in the art,.but I do not deem it necessary to set them forth at length herein.

My invention resides in the apparatus for carryingthe same into effect, a preferred form of which is shown in the accompanying drawings forming a part hereof, in which;

Figure 1 is a side elevation of a cigarette machine, otherwise of conventional construction to which a specific embodiment of cigarette pasting device has beenapplied. Fig. 2 is a plan view of the same. Fig. 8 is an enlarged sectional view taken substantially on the line 33, Fig. 2; and Fig. 4 is an enlarged transverse sectional elevation taken substantially on the line 14, Fig. 2.

Throughout the various views of the drawings, similar reference characters, designate similar parts.

In the practice of my invention I produce a paste which, preferably after it has cooled and set, becomes solidor substantially solid and preferably not sufficiently liquid to flow freely, although with an apparatus constructed to provide means for handling it in a liquid or semi-liquid condition, it may be thus employed. In the application of the paste to the cigarette seam, heat is applied to the paste, preferably sustained in a vessel of appropriate shape, so as to cause the heated paste to flow, preferably rendering it sufliciently liquid to allow it to adhere, by means or instrumentalities to be described, for a sufficient length of time to permit it to be transported to its final point of application to the cigarette seam, without gripping or change of position. The paste having been rendered substantially semi-liquid or fluent, means are employed for transporting it in this condition in a regulated amount or quantity which means not only regulates the amount to be applied to the lap of the paper strip, but the exact extent of predetermined surface, to which the paste is to be applied.

It is contemplated in the practice of my invention that the paste be applied by means which move co-incidentally with and in the same direction as the lap of the paper strip. After the paste has been applied to the lap of the paper strip the seam will be retained in the cigarette rod and passed through means in which heat is absent, which lays down the lap of the strip under pressure and simultaneously cools, dries, and sets the paste and irons the seam. In this way, in its broad aspect, is my invention carried out.

Now referring to the preferred form of my apparatus, 1 designates a cigarette machine of conventional or suitable type. As shown, this machine is provided with the usual belt or carrier 2 which runs over suitable guide rollers 3 and 4 mounted in convenient or conventional manner and through forming blocks 6 and 7. In this form of machine a paper strip is fed so that it rests upon and lies over the band or carrier 4, and the tobacco is fed to and upon the paper strip. The forming blocks 6 and 7 which are of sufiicient length and suitable shape, together with other instrumentalities usual in machines of this class, causes both the belt or carrier and the paper strip supported thereon to be turned over and inclose the tobacco rod, leaving one edge or lap of the strip, and carrier partly or wholly raised as shown in-Fig. 3; and a continuation of this movement of the tobacco rod, paper strip and carriers (toward the right-hand of Fig. 1) through the means provided for it in the forming blocks 6 and 7 pressing the upwardly lying and pasted lap of the paper strip down upon the opposite lap of the paper strip, the construction and interior formation of the channel formed by the blocks 6 and 7 through which the cigarette rod passes, shifting off the belt or carrier, so that when the cigarette rod is passed out of the channel formed between the blocks 6 and 7 it is separated from the bite or grip of the belt or carrier and is free to be treated as desired such as being cut into the desired lengths and subjected to other operations usual in this class of machine.

The pasting wheel 9 is mounted on a shaft 10 with a proper cone bearing 11 which runs in a suitable pedestal 12 in the machine 1 and the wheel 9 extends over a portion of the plate 7, as shown in Fig. 3. The 'shaft 10, at its upper end, has a suitable center in which is inserted a screw 13 held in a suitable support 14 so that the shaft 10 runs true. This shaft 10 is driven by a fixed pulley 15 which is run by a suitable cord or belt 16 which runs on a corresponding pulley 17 on a shaft 18, and this pulley 17 is connected to a bevel gear 19 which is run by a second bevel gear 20, which is connectedto a pulley 21 which is run by a belt 22'driven by another pulley 23, and this pulley 23 is fixed to the main shaft 24 of the machine. The shaft 24 also carries a worm 25 fixed thereon which meshes with a corresponding Worm gear 26 that drives a bevel gear 27 whichmay be made integral therewith, and this bevel gear 27, drives another gear 28 on a horizontal shaft 29 mounted in suitable bearings 30, and at the other end of this shaft 29 is a ring 31 which I revolves under a reservoir 32 supported by the support 14, or other suitable means, so that the paste passes from the lower end of the reservoir 32 onto a revolving ring or hollow wheel 31. Heat is applied to the ring 31 in any convenient manner as by means of a suitable burner 33 which is supplied with gas through a pipe 34, which is suitably connected for this purpose.

When the machine is in use, the rod 8 passes through the forming blocks 6 and 7 in the belt 2, in the conventional manner, and at the proper time the pasting wheel 9 rubs against the upper layer of paper of the seam of the rod 8 and pastes the seam with hot paste, which it receives from the heated ring 31 that passes under the reservoir 32. The seam is then closed, in the usual manner, and when it emerges from the block 7 it is dry and firm and the paste is set so that the rod operates in the usual way when passing through the remainder of the machine.

While I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all the structures that come within the scope of the annexed claims.

Having thus described my invention, what I claim is 1. In a device of the class described, a reservoir, a ring revolving thereunder, means for heating the ring, and a paste applying roller adapted to take the heated paste from the ring and apply the paste in a heated condition to a seam.

2. In a device of the class described, a reservoir, a ring passing thereunder, and means for heating the ring, a pasting Wheel adapted to take heated paste from said ring and apply same to a seam, and means for holding a paper Web so that it Willreceive said heated paste and then force the parts of the seam togetherwhile the paste is green and hot and allow the same to set Without the aid of a heating or drying device. a

3. In a device of the class described, a reservoir, a ring disposed beneath the same and forming the bottom thereof, means for revolving said ring and means for applying heat to the interior of said ring.

4. In a device of the class described, a reservoir, a ring disposed beneath the same and forming the bottom thereof, means for revolving said ring, means for applying heat to the interior of said ring and a paste applying roller disposed at right angles to said ring With its periphery in cont-act there With to take the heated paste from the ring and apply the'saine in a heated condition to the same.
